Research has shown that exposure to high levels of noise can result in physical complications such as debilitating heart attacks, stroke 2 , and diabetes 3. At the same time, noise pollution also puts a strain on our mental state, which can lead to headaches, depression 4 , and accidents from weariness 5.

Urban and industrial noise pollution is present in virtually every country in the world. Noise pollution studies are therefore needed to find solutions to improve the quality of life in cities. This book contains eighteen chapters that address the problem of noise in urban and industrial environments.

Effective noise control strategies

In industrial settings, noise from this equipment frequently exceeds OSHA limits for hearing safety while also impeding communication. Without noise control remediation, local noise ordinances at plant property lines may be exceeded. IAC Acoustics' line of acoustic enclosures are an effective and efficient way to address these problems. IAC Acoustics test cells are commonly used in both product development test applications as well as production test applications, such as: electronic audio component manufacturing, automotive development and testing and destructive pressure testing of materials for the healthcare field. IAC screens and enclosures are available in a wide range of standard finishes and colors. All rights reserved. Toggle navigation.

Use of this web site signifies your agreement to the terms and conditions. Active noise control: a marriage of acoustics and control Abstract: In a response to a growing demand for environments of 70 dB or less noise levels, many industrial sectors have focused their attention on the development of quality products with some form of noise control cancellation system. Automotive manufacturers, aircraft designers; engine manufacturers; appliance industries; producers of heating, ventilating, and air conditioning systems, etc. Active noise control ANC has proven to be the most effective technology, especially for low frequency excitations that the human is more sensitive to.

In short, it is used to reduce industrial noise and vibration control across the end-use industries. Industrial noise is primarily considered across the manufacturing, healthcare, and construction industries where the sound levels are often greater than 85 decibels. Additionally, there are circumstances where the industrial machines produce sounds in the range of 70 to 75 decibels, which is primarily produced from public address systems and exterior noise intrusion. Sometimes, such industrial machines are pre-installed with noise control systems such as HVAC noise control and pressor noise control. This results in increased risk of noise health effects and increased need for industrial noise control products in the industrial activities.

It seems that you're in Germany. We have a dedicated site for Germany. Excessive noise levels are generally acknowledged to have adverse effects on our environment. Studies indicate that excessive noise levels can cause fatigue in exposed individuals, lower efficiency and productivity, impaired speech communication, and hearing loss. Excessive noise is almost everywhere today - in the office, in schools, hospitals and other institutional facilities, in all classes of public buildings, and in our factories.

Acoustics is a branch of physics that deals with the study of mechanical waves in gases, liquids, and solids including topics such as vibration , sound , ultrasound and infrasound. A scientist who works in the field of acoustics is an acoustician while someone working in the field of acoustics technology may be called an acoustical engineer. The application of acoustics is present in almost all aspects of modern society with the most obvious being the audio and noise control industries. Hearing is one of the most crucial means of survival in the animal world and speech is one of the most distinctive characteristics of human development and culture.

Exposure to high levels of noise may cause hearing loss, create physical and psychological stress, reduce productivity, interfere with communication, and contribute to accidents and injuries by making it difficult to hear warning signals.
